2.5A, 100V High Frequency Half-Bridge Gate Driver



The MP1921A is a high-frequency, 100V, half bridge, N-channel power MOSFET driver. Its low side and high side driver channels are independently controlled and matched with a time delay of less than 5ns. Under-voltage lockout on both high side and low side supplies force their outputs low in case of insufficient supply. The integrated bootstrap diode reduces external component count.
